Rv/mobile generator sets

AC Load Lead Connections

Each set has four color-coded load leads. The black

leads (L1 and L2) are hot, the white lead (L0) is neutral

and the green lead is the hazard ground. Route the load

leads directly from the junction box to the vehicle AC

circuit or transfer-switch connection. All installations

require that the load leads be routed through flexible

conduit from the generator end bracket to the junction

box location.

The load lead junction box must be

accessible for servicing and inspection.

Keep load lead circuit away from the generator,

specifically fuel and exhaust system components.

All field-supplied wiring must be capable of withstanding

temperatures of 167_ F (75_ C).

AC load lead L0 (white or gray) is always the neutral lead

on Kohler generator sets. Make sure the neutral of the

Figure 6-17. Transfer Switch Connections, 3-Wire AC Circuit

AC circuit in the vehicle is connected to the lead L0

(white or gray). If equipment ground-type plugs and

receptacles (3-pronged) are used in the vehicle, the

green wire must be connected to the U-shaped pin. On

vehicles which also have provisions for using an outside

AC power source, the neutral as well as the hot (or

black) leads must be completely isolated from the

generator set when power is switched to the outside

source. See Figure 6-17.

Use a triple-pole, double-throw transfer switch rated for

the calculated load of the RV to transfer the load from

one source to the other. Install a ground-fault circuit

interrupter in the wiring system to protect all branch

circuits.

The AC load circuit of the generator set must be

protected by a circuit breaker(s) against overload or

short circuit.
